We don’t have to tell you why adjustable dumbbells are some of the best home gym equipment out there, right? You already know they help you save space and money, and that they provide you the same strength training benefits as free weights. OK, good. Now you just have to find the best adjustable dumbbells, which is easier said than done considering there are so many options.
Our EzBlock adjustable dumbbell review looks at one of the newest kids on the block who’s looking to convince you that they’re better than the PowerBlocks and NÜOBELLs we’ve all come to know and love. But are they?
Read on to find out.
We Never Take the Ez Way Out With Our Dumbbell Reviews
Coop and the rest of the Garage Gym Reviews team have developed a foolproof way to test and review everything from barbells and weight plates to adjustable weights like the EzBlocks. That involves looking at everything from the weight increments to the ease of use, as well as identifying what type of lifters may benefit from the equipment.
We’re able to do that because we’re a group of certified personal trainers, CrossFit coaches, and competitive athletes who work with powerlifters, bodybuilders, and weekend warriors.
EzBlock Adjustable Dumbbells
EzBlock Dumbbells
Product Highlights
- Adjustable dumbbell ranging from 6 to 70 lbs
- Adjusts in seconds with the twist of the handle
- 1-kg (2.2-lb) adjustments
- Indicator on block shows how much it weighs
Pros & Cons
Pros
- 21-kg weight increments
- Small footprint in your home gym
- Full steel construction
Cons
- Cannot drop the dumbells
- Expensive
- Maximum weight only goes to 70 lbs which could be to light for certain movements for some people
Bottom Line
This product is expensive, but it may be worth it if you are able to make the investment. Looking at other adjustable dumbbells, these have a lot to offer, like a more precise adjustment.
A Quick Look at the EzBlock Adjustable Dumbbells
The EzBlock Adjustable Dumbbells are made by EzToned, a New Zealand-based company that makes home workout equipment that allows you to workout anytime, anywhere. And adjustable dumbbells fit right into that category, which is just one of the many reasons we’ve recommended them to most home gym owners.
The thing that separates the EzBlocks from the dozens of other adjustable dumbbells is that they have the “most precise” weight increments on the market—2.2 pounds, or 1 kilogram. You simply turn the dial to increase the weight all the way up to 70 pounds, or 32 kilograms.
The dial adjustment mechanism is very similar to what we see on the Bowflex SelectTech 552 Adjustable Dumbbells, which is one of our favorites because of their ease of use.
My Tips
- These are sold individually or in pairs, so make sure you pick the right one at checkout.
Pros:
- Replaces dozens of traditional dumbbells
- Changing weight increments is as easy as turning the handle
- Most of the dumbbell, outside of the handle, is made of durable steel
Cons:
- No knurled handle
- $400 per individual dumbbell, or $700 for pair is fairly expensive
- Doesn’t come with an expansion kit to create heavier weights

Are the EzBlock Adjustable Dumbbells Worth It?
The EzBlock Adjustable Dumbbells are sold individually and in pairs, but for argument’s sake let’s pretend you’re buying the pair (because who wants just one dumbbell?). Two EzBlock Adjustable Dumbbells will set you back $700, not including shipping and handling.
That’s a lot of money, so much so that the EzBlocks are one of the most expensive adjustable dumbbell sets on the market. But we’re not against paying top dollar for premium goods, and there are a few people who we think may get their money’s worth out of the EzBlocks (and we’ll get to that in a bit). Here’s who we think will enjoy the EzBlocks, and who may want to look elsewhere.
Great for:
- Those looking for a compact set of adjustable weights
- Anyone who wants an adjustable dumbbell that has a quick adjustment mechanism
- People who want to get a full-body workout with one piece of equipment
- Lifters looking to achieve progressive overload
Not recommended for:
- Those looking to lift weights heavier than 70 lbs
- Anyone on a budget
- Lifters who want or need knurling on their dumbbells

“The World’s Most Precise Dumbbell” — Here’s Why that Matters
EzToned’s main selling point with the EzBlock Adjustable Dumbbells is that they’re the “most precise dumbbell” due to the 1 kilogram (again, for us Yanks, that’s 2.2 pounds) weight increments that start at one kilo and go all the way up to 32 kilograms, or 70 pounds. If you’re saying, “So what?” allow this certified personal trainer to tell you why that matters.
If you want to build muscle or get a stronger bench press, you need to achieve what’s known as progressive overload, which mainly involves increasing either the weight you train with or the number of repetitions you do for a certain exercise.
Since we’re talking about dumbbells, we’ll use biceps curls as an example and that your max is around 50 pounds, but you want to get that number up so you can get mountain peak biceps. Most adjustable dumbbells are going to have 5-pound increments, and while you can probably lift an additional five pounds, you may not be able to get many reps in.
With the EzBlock Adjustable Dumbbells, you could up the weight by only 2.2 pounds and do a lot more curls, which translates to more muscle and strength gains. And this philosophy can be applied to goblet squats, tricep extensions, shoulder presses, and so on.
In other words, calling these the “World’s Most Precise Dumbbell” isn’t just a marketing scheme (though if we’re being honest that’s certainly part of it), and the ability to have such incremental weight options could be a huge benefit to anyone looking to make gains.
It also makes it a great option for beginner lifters who want to work with lower weights, since the EzBlocks start at only 2.2 pounds.
Frankly, I’m a little surprised we haven’t seen this from any of the major home gym equipment manufacturers. Is it a necessary thing? Not really, but it’s certainly genius in my personal and professional opinion.
You Spin the Handle Right Round (Like a Record)
The other thing I really like about the EzBlock Adjustable Dumbbells is their ease of use, especially when it comes to adjusting the weight. You simply put the dumbbell in its tray, make sure all the plates are properly lined up, and twist the handle to select your desired weight.
“Probably the quickest to change out of any adjustable dumbbell,” says Garage Gym Reviews founder Coop, who tested these out. “Yes, even faster than NÜOBELLs I would say. Probably my favorite feature of the dumbbells.”
This is similar to what we see on the Bowflex SelectTech dumbbells, and even the NÜOBELLs. Having this is a blessing because you save time putting plates on and off the dumbbell, like you see on the Ironmaster Quick-Lock Adjustable Dumbbells.
This quick change comes in handy when you’re doing supersets (when you do two or more exercises back-to-back with minimal rest) or high-intensity interval training.
One criticism of the handle is that it has a rubber grip. Now, I get that nobody is going for an Olympic lift or trying to set a powerlifting record with these things, but it still would’ve been nice to have a knurled handle to make these things feel like a traditional dumbbell. But, that’s just a personal preference (though it matters to many lifters).
70 Pounds Maximum Weight — Is it Heavy Enough?
One feature you should consider when buying an adjustable dumbbell, or even an adjustable kettlebell, is the maximum weight since you’ll want something that can always challenge you. The EzBlock Adjustable Dumbbells max out at 70 pounds, which, for the vast majority of home gym users, will probably be enough.
Looking at the dumbbells, it doesn’t seem like there’s much room for a future expansion kit to make these heavier (though I could be wrong).
If you’re someone who easily reps more than 70 pounds on most moves, we’ll have more recommendations later on but you might be better off with a loadable spinlock dumbbell like the Rogue DB-15. They’re not as convenient as adjustable dumbbells, but you can make them as heavy as you like.
So how do these dumbbells feel in use? Here’s what Coop had to say: “They’re very bulky no matter the weight. So, even at their lightest, they still take the same width as they do at their heaviest.”
That may not make a difference during most moves, but Coop said it was difficult for him to get a comfortable grip on them when attempting dumbbell swings.
Durability
Adjustable dumbbells aren’t known for being the most durable pieces of equipment, especially when compared to traditional hex dumbbells. That’s because many use plastic or other cheap materials in certain parts, such as the selector pin (for those that use one) or the covering that protects the cast iron plates.
We know nobody ever plans on dropping their dumbbells (and if you’re that type of person, just stop), but accidents happen. But when you’re dealing with something that has plastic on it, those accidents could result in a busted dumbbell.
Aside from the ergonomic rubber grip, the EzBlock Adjustable Dumbbells are made with steel (we weren’t able to track down what type of steel they used). Do we recommend you drop it to test out its durability? No, leave that to us and our YouTube videos. That said, we’re more confident that these could take a beating compared to most other adjustable dumbbells.
EzBlock Adjustable Dumbbells vs Bowflex SelectTech 552
Bowflex SelectTech
Bowflex Results Series 552 SelectTech Adjustable Dumbbell
Product Highlights
-
Replace 15 sets of weights
-
Weights adjust from 5 to 52.5 lbs
-
Affordable at $479/pair
-
Weight adjustments in 2.5- and 5-lb increments
Pros & Cons
Pros
- Replace 15 sets of weights
- Weights adjust from 5 to 52.5 lbs
- Extremely affordable at $479/pair
- Weight adjustments in 2.5-lb increments
- One of the fastest changing dumbbells on the market
- Come with a stand
Cons
- Max weight is 52.5 pounds
- Wide footprint remains the same at any weight
- Not meant to be dropped
Bottom Line
If you want affordable adjustable dumbbells, the Bowflex pair are a great option. Although they don't get very heavy, they are a great option for beginners and those who do not need more than 52.5 lbs per hand.
Editor’s Note: As of June 5, 2025, Johnson Health Tech Trading has recalled the Bowflex 552, 52.5 LB Adjustable Dumbbells and the Bowflex 1090, 90 LB Adjustable Dumbbells due to potential impact hazards from the plates dislodging during use. If you own the Bowflex 552 Adjustable Dumbbells or the 1090 Adjustable Dumbbells, you may be eligible for a refund or replacement. To learn more and start the recall process, read the Consumer Product Safety Commission statement here.
The EzBlock Adjustable Dumbbells remind us of the Bowflex SelectTech 552s because both simply require you to twist the handle to change the weight, going from the starting to max in under five seconds.
That’s about where the similarities end, however. The Bowflex dumbbells are made with a lot more plastic, and the weight set isn’t nearly as vast as the EzBlocks (as the name suggests, you start at 5 pounds and go all the way up to 52.5).
That said, the 552s are under $450 per pair on Amazon, which is a lot more budget-friendly than the EzBlocks. And they’re still a high-quality dumbbell, you just have to take extra care not to drop them.
If you have the money for the EzBlocks, we’d honestly recommend them since you’re getting a higher weight range and more durable construction. If you don’t, the Bowflex dumbbells will serve you just as well (just know there’s no expansion kit, so 52.5 pounds is the heaviest you’ll be able to go).

EzBlock Adjustable Dumbbells vs. NÜOBELL Adjustable Dumbbells
Nüobell Adjustable Dumbbells
NÜOBELL Adjustable Dumbbells
Product Highlights
- All-in-one adjustable dumbbell
- Weight ranges from 5 to 80 lbs
- Easy to use
- Feels like a standard dumbbell
Pros & Cons
Pros
- Feels like a regular dumbbell in hand
- Easy quick-change adjustments
- Knurled handle
- Comes with a stand
Cons
- Can be tricky to get in the stand
- Unsure of structural integrity
- Pricey
Bottom Line
These are great for people who want an easily adjustable dumbbell pair that feels more like a traditional fixed dumbbell
The NÜOBELL Adjustable Dumbbells retail for just under $750, not including shipping and handling, compared to the $700 asking price for the EzBlock Adjustable Dumbbells. If you’re looking at this price range, we don’t think $50 is going to make or break the bank.
The NÜOBELLs feel much more like a fixed dumbbell than the EzBlocks, thanks in large part to the knurled handle. Starting at five pounds and going all the way up to 80, in 5-pound increments, they replace 16 pairs of dumbbells, so not quite as much as the EzBlocks but still quite a bit (and you’re getting a heavier maximum weight).
Unless the EzBlocks’ one-kilogram weight increments are very appealing to you, we’d honestly recommend the NÜOBELLs. They have the same quick change handle as the EzBlocks, the knurling is a nice touch, goes all the way up to 80 pounds, and while there’s some plastic, they’re largely made of durable steel.

EzBlock Adjustable Dumbbells vs PowerBlock Adjustable Dumbbells
PowerBlocks
PowerBlock Elite Series Adjustable Dumbbells
Product Highlights
- Change the weight in 2.5- or 5-lb increments
- Up to 70 lbs per hand
- Add extension kits for up to 90 lbs per hand
- Extremely durable
Pros & Cons
Pros
- Can change weight in increments of 2.5 or 5 pounds
- Weight goes up to 90 pounds with add-ons
- More durable than most adjustable dumbbells
Cons
- Rectangular shape might throw some people off
- Returns subject to 20% restocking fee
- Not as comfortable as using fixed dumbbells
Bottom Line
PowerBlock Elite dumbbells go up to 70 pounds (90 pounds with the extension kit), can be changed in 2.5- or 5-pound increments, and replace 16 pairs of dumbbells. These adjustable dumbbells are also priced under $500. PowerBlocks are ideal for anyone seeking a durable adjustable dumbbell for at-home workouts.
There are multiple PowerBlock Adjustable Dumbbell options available, such as the PowerBlock Elite Series and the Power Block Pro Series. We don’t have time to get into all the differences between the two, but just know the PowerBlock Pro has a wedge shape while the Elite has a closed-handle design (you can learn more in our PowerBlock Adjustable Dumbbells review).
Whichever you go for, you’ll have a maximum weight of 50 pounds, but that doesn’t include the expansion kit that allows it to go up to 70 pounds, matching the EzBlocks’ weight. There’s also an additional PowerBlock expansion kit that can make both models go up to 90 pounds per hand.
If you went with the Pro Series, you’d end up paying just about the same as the EzBlocks after adding the first expansion kit. The Elite Series, on the other hand, ends up being about $100 cheaper with the first expansion kit, and just $100 more expensive if you add on the second.
The PowerBlocks aren’t quite as durable as the EzBlocks (though the urethane coating does protect them from shoulder-height drops), and the selector pin is quick though not as swift as the easy-turn handle.
If you’re looking for value, we’d say go for the PowerBlocks. You also get a five-year warranty with the PowerBlocks, compared to the three-year coverage offered by EzToned.
One big caveat is that the PowerBlocks are not shaped like a traditional dumbbell, whereas the EzBlocks are more reminiscent of what you’d find in a commercial gym. That may make a difference to some people, especially those with larger mittens who may find their range of motion shortened by the PowerBlocks’ closed-handle design.
Other Adjustable Dumbbell Options
NordicTrack iSelect Voice-Controlled Adjustable Dumbbells: Starting at 5 pounds and going all the way up to 50, these adjustable dumbbells can be connected to your Alexa device so you can change the weights with a simple voice command. That’s…fun? There’s also a knob if you prefer the ancient technique of using your hands to adjust weights. We haven’t gotten our hands on them yet, but they sell for $600, which is more expensive than most with similar weight ranges.
Ironmaster Quick-Lock Adjustable Dumbbells: We didn’t do a head-to-head comparison with these because it wouldn’t be fair. The Ironmaster dumbbells use special plates that, in full honesty, are a bit of a hassle to put on and off, which also means having to do math to make sure you’re putting the right amount of weight on the handle (not that that’s difficult, but it is annoying mid-workout). They’re a fine dumbbell, but if you’re looking for convenience these ain’t it, dawg.
Financing, Returns, Warranty
EzToned offers financing options through Affirm and ShopPay starting at $36.13 a month.
You have 30 days from the day of delivery to return your EzBlock adjustable dumbbells for a full refund, even if they’ve been opened and used.
There’s a three-year warranty on the EzBlock adjustable dumbbells that covers every part of the equipment from any damages or manufacturing defects.
Ordering and Assembling the EzBlock Adjustable Dumbbells
EzToned’s website states that the EzBlocks may take 8 to 10 weeks to ship, but, if you look at their shipping policy it states that U.S. orders take, on average, 3-10 business days.
And there’s no assembly required. Simply take them out of the box and start lifting.
Customer Reviews
The EzToned website has more than 400 reviews on TrustPilot, but most of them seem to be about the company’s EzBar home workout system (which is similar to the Gorilla Bow). That said, the company does have an average rating of 4.5 stars and many reviewers rave about the excellent customer service and products.
Final Verdict of Our EzBlock Adjustable Dumbbells Review
The EzBlock Adjustable Dumbbells are, in our opinion, a worthy contender in the adjustable dumbbell category. The ability to change weight increments can positively impact many people’s strength training journey, and the additional handle only adds to these dumbbells’ versatility and value.
The use of all-steel construction is another huge plus in our book, as is the quick change handle.
Our few criticisms, the lack of a knurled handle and expansion kits, are minor in the grand scheme of things and probably won’t matter to many home gym owners.
At the end of the day, if you’re looking for a high-value and durable adjustable dumbbell that can help you achieve the strength and muscle gains you’re looking for, you can’t go wrong with the EzBlock Adjustable Dumbbells. Plus, you have 30 days to try them out for yourself so what do you have to lose?

EzBlock Adjustable Dumbbells FAQs
Are adjustable dumbbells worth the money?
Absolutely! Adjustable dumbbells may be expensive upfront, but many manufacturers offer financing options to help make them more affordable. Plus, you’d spend the same amount of money (probably more) on a set of fixed dumbbells that would take up much more space.
How heavy should adjustable dumbbells be?
As heavy as you need them to be. Adjustable dumbbells can be as heavy as 50 pounds, and all the way up to 90. How much weight you need is going to depend on your fitness levels and future fitness goals.
Which adjustable dumbbells can be dropped?
Ideally, you’d never drop your adjustable dumbbell, or any other gym equipment for that matter. Repeated drops can result in dents and other damage to barbells and dumbbells. That said, the EzBlock Adjustable Dumbbells are made with steel that can hold up to drops better than plastic, which you find on many adjustable dumbbells.
